PCB Piezotronics,
Inc. announces the launch of their new probe microphone for R&D
engineers who need to measure sound pressure in confined areas.
The probe tip diameter is extremely small measuring 0.050"
(1.3mm) which enables white goods, telephone, headphone, loudspeaker
and musical instrument manufacturers to make measurements in
small, confined and difficult-to-access areas that cannot be
accessed using traditional microphones, which are typically larger.
The small size of the probe tip also allows near field measurements
with minimal disturbance of the sound field. This enables more
accurate test results.

The probe microphone
(Model 377B26) comprises four components: microphone, preamplifier,
housing and several probe tips of different lengths. The components
work together to provide a maximum operating temperature of 800°C,
much greater than traditional test & measurement microphones.
The high temperature capability and small diameter make it an
excellent choice for HVAC manufacturers and test engineers performing
leak detection tests at elevated temperatures. "We are very
excited about the new probe microphone. The combination of the
elevated temperature range and small form factor of the probe
tip, allows this unique microphone design to be used in a plethora
of applications where traditional microphones would not be feasible"
states Mark Valentino, Product Marketing manager for the acoustics
division at PCB.

Total system
cost is reduced with the prepolarised design, which is powered
by ICP&REG; or any 2-20mA constant current supply. This allows
engineers to use existing 2-20mA low-cost power supplies and
coaxial cables which are less costly than 200V power supplies
required for externally polarised microphones. An additional
benefit is interchangeability with existing ICP&REG; accelerometers,
load, force, torque and pressure sensor set-ups.
